In Thursday’s (16 June) show though, she wakes up and reveals that she feels like she’s made a mistake, telling viewers in the Beach Hut: “That’s really not like me at all. Why couldn’t we have just gone to sleep?”

Later, she’s seen breaking down as she confides in Sophie Gradon, admitting: “I wouldn’t even do that if I was in a couple with someone. I just feel like everyone’s going to judge me. But look it’s not like me at all, it’s so out of character.

“I’ve never had a one-night stand or anything. Even when I’ve been seeing guys, I don’t just sleep with them on the first night.”

Alex, meanwhile, was more concerned that he’d ruined his chances of getting together with Olivia Buckland.

After learning of Zara and Alex’s rendezvous, Olivia admitted: “I’ve already been made to feel like an idiot once in here and now I’ve been made to feel like an idiot again.

“Kady came downstairs and told me that Alex and Zara had slept together and I was a bit shocked. I was sort of shocked and not shocked because I always think the worst and that’s what I was thinking.

"But it wasn’t nice and it did piss me off and I was a bit like ‘Zara, what are you doing', that was probably the worst thing to do.”

The episode ends in a confrontation between Zara and Olivia, who both vent their feelings about the past 24 hours of drama in the show.

Find out how it goes down between them in Thursday’s ‘Love Island’, airing at 9pm on ITV2.

Chloe Jasmine and Stevi Ritchie ('The X Factor')

Chloe and Stevi first met while sharing a house together, during the 2014 series of 'The X Factor'.

Although they briefly split up when the series was still on the air, they rekindled their romance before long, going on to become 'Celebrity Big Brother' housemates, and appear in a series of totally-natural and not-staged photo sets, just like this one.

The third series of 'I'm A Celebrity' - otherwise known as 'the one where it really started to get good' - kicked off in 2004, and sparked one of the UK's biggest celebrity pairings of the 21st century.

Off the back of 'I'm A Celeb', Katie and Peter were omnipresent for years, with reality shows, fragrances and yes, even an ill-advised album to their name. They split in 2009, and recently reconciled, after a feud which lasted more than five years.

The first real love story of 'Big Brother', Helen and Paul first met on the reality show's second series in 2001, eventually staying together for five years.

Here they are with Lorraine Kelly, the lucky ducks.

Among the most famous 'Strictly' curse victims, Ben split from his long-term partner shortly after being partnered with Kristina, though the two were insistent they didn't get together until long after the break-up.

When we're blowing out the candles on our birthday cake this year, we'll be wishing for a re-enactment of this exact photo, with us in place of Kristina.

Atomic Kitten and 5ive weren't the only ones brought together by 'The Big Reunion', with Natasha and Ritchie getting together during the show's UK tour, though they announced their split in early 2016.

Truly, there is nothing left to say about this pair.

Rebecca Ferguson and Zayn Malik ('The X Factor')

Yeah, we'd forgotten about this one too, but shortly after the seventh series of 'X Factor' wrapped up in 2010, it was revealed that runner-up Rebecca Ferguson had been knocking boots with One Direction singer Zayn Malik.

Despite their seven-year age gap (Zayn was just 17 at the time), they stayed together for a number of months, with the 'Pillowtalk' singer eventually going on to date Stephanie Davis and Perrie Edwards.

Another case of the 'Strictly' curse having a happy ending, Rachel revealed she and her husband were parting ways during her appearance on the BBC series in 2013.

She and Pasha announced 10 months later that they were an item.

Steven Goode and Kimberly Kisselovich ('Big Brother')

Who could forget Steven and Kimberly's romance, eh? NOT US, because the thought of him whispering "open it" to her in the 'BB' bedroom is still BURNED IN OUR MEMORIES for the rest of our days.

Steverly tied the knot a year after leaving the 'BB' house, but months later, it was reported that they had already split.

Stacey Solomon and Steve-O ('The Jump')

Sometimes reality TV can throw us a curveball, like when 'Jackass' prankster Steve-O and 'Driving Home For Christmas' warbler Stacey Solomon got together on 'The Jump'.

Sadly, they split the following summer, admitting they struggled with their long-distance relationship.

Tamera Foster and Sam Callahan ('The X Factor')

'The X Factor' might not seem the most likely place to find romance, but Tamera Foster and Sam Callahan made a good go of it after meeting during 2013's series.

However, they split up a year later.

Chantelle and Preston ('Celebrity Big Brother')

Theirs was the reality TV romance the whole country was rooting for. It had it all, drama (Preston had a girlfriend when they first met, meaning they dismissed their 'CBB' flirting at the time), romance (nothing sets the mood like George Galloway pretending to be a cat in the next room) and a few bumps in the road (remember when he stormed off 'Buzzcocks', though?).

Their highly-public split was followed a few years later by both of their arrivals in the 'Ultimate Big Brother' house, and while it looked like a reunion could be on the cards, it eventually never came to fruition.

Seriously, there must be something in the water over at the 'Strictly' studios, with Georgia May Foote and Giovanni Pernice the latest pairing to reveal that their relationship extends past the dance floor.

Charlotte Crosby and Gaz Beadle ('Geordie Shore')

A reality TV couple so on-again-off-again no one - including them - is ever actually sure what their relationship status is at any given time.

Now husband and wife, David and Frankie met when he swapped his football boots for ice skates for his appearance on 'Dancing On Ice'.

The two were partnered together, eventually revealing that they were an item.

Samia Ghadie and Sylvain Longchambon ('Dancing On Ice')

Slightly more scandalously was the union of 'Dancing On Ice' pair Sylvain Longchambon and Samia Ghadie, particularly as when they got together he was still dating Jennifer Metcalfe... who he'd been partnered with just two years prior.

Pete Bennett and Nikki Grahame ('Big Brother')

Arguably the most unlikely 'BB' couple ever, Pete and Nikki's romance was a nontheless endearing one, and we loved watching them grow close during their time in the house.

Sadly, in the months that followed, Nikki revealed that their relationship hadn't lasted in the outside world, admitting at the time: "I really hope that he didn't use me. I would like to think that he had genuine feelings for me but who knows? I don't know what to think."

Denise Van Outen and Lee Mead ('Any Dream Will Do')

Proving that reality TV romances aren't just for the contestants, 'Any Dream Will Do' judge Denise Van Outen surprised viewers when she revealed that she was in a relationship with the show's eventual winner, Lee Mead.

The pair were together for six years, even having a daughter in 2010, but announced they were going their separate ways in July 2013.

Grace Adams-Short and Mikey Dalton ('Big Brother')

The 'BB' couple that have managed to go the distance are also the ones who kept the lowest profile at the end of the show (funny that, isn't it?).

Grace and Mikey have been together since the end of their series in 2006, and have two children.

Sue and Alex Tatham ('Blind Date')

Proving that TV romances are nothing new, who could forget Sue and Alex Tatham, who tied the knot in 1991, after meeting on an episode of 'Blind Date'. Our Cilla even attended the wedding which, frankly, we're really jealous about.
